A Look At A Hand Ported Stock LS3 Intake

- This is my first ever try at porting a stock plastic LS3 intake. Opened it up to accept a 102-103mm throttle body, remove EGR tube, removed center posts, sanded down and smoothed out ridges and casting flashing. Will be tested on a stock cube, stock head, big cam LS3 C6. After that it will be tested with aftermarket cylinder heads.
Porting services available at Skunk Workz Garage, look for us on Instagram or send us a message here on CZcams.

The best intake GM ever made. It’s tough to get any aftermarket rec port intake to make the low end the LS3 intake does only Fast but they’re $1200
Thank you for that. I couldn't understand what the heck everyone was doing radius rods for. It had no explanation. I get it now. Thank you
Nice work mate just what I was looking for I have a 6.0 being stroked to 408 huge cam and was looking to port my intake can’t justify the price tag for a aftermarket intake for just an almost 30hp gain have ported a shitload of heads over the years and was looking to see if anyone had ported a stock manifold what was it like cutting the center posts out looks like it would have been a tight shit of a job
Whats the easiest way to cut out the center supports
1786 Vlogs a long sawzall blade then sanding by hand
@@c5natie1 how did you fill the hole after cutting them out?

@@c5natie1 how do you support it while it cures?
Nice video, Thank you, How did it dyno? Could you tell a difference if what was the gain?
Robert Preston it made 14hp and 2ftlbs over a stock manifold. It made 2hp less at peak than a FAST 102 but made more power average throughout the power curve and 5ftlbs more peak torque but with a much broader torque band. The dyno video comparisons are on my channel.
Robert Preston it made 570hp/512ftlbs on a stock LS3 with a 244/256 112lsa cam.
I am adding a RCR stlye intake with a smaller cam. 220/230 117LSA. Will I see additional gains with the intake? My tuner says it won't.
Nice work have you done a ls7 intake yet?
Crystal Malek thanks. Not yet but maybe soon
What kind of epoxy did you use?
Where did you purchase the 1/4” half round rods?
How did you reach the back?
does this need a tune ?
not necessarily but a tune would help maximize the gains.
I’m doing the same thing to my LS3 Manifold... where can I get the TB gasket for this type of porting ? Thanks 👍🏻
Holley makes the gasket. They fit 92-102mm openings. I buy them through Summit Racing
Part #508-20 They're like $8
Nayt83 Thank you so much... I just received it... also ordered the 102mm TB 👍🏻
I want to attempt this. I have some experience with porting. My question is, In your opinion would it benefit my c6 with out the cam? Didn't find much info out there
You won't see gains without a cam because you're not using the added airflow. The engine doesn't demand it. The stock LS3 intake will supply more than enough airflow for a stock car. I would not bother porting unless you have a cam and or heads.
